I was trying to use route-map for some bgp neighbor what is configure in vrf. I have noticed the route-map is working only for OUT filter, but IN filter is not working. Ex: I have allowed the neighbor 10.40.40.2 to rcv specific IP inbound IN route map(GGC_CUSTOMER_IN). but it is also receiving the IP prefix 10.0.0.0/23 from 10.40.40.2 which is not permitted by the route-map IN. On the other hand the outbound route-map(GGC_CUSTOMER_OUT_L3) is working good in the same neighbor.
Now the question is why the neighbor is not doing according the route-map, how it is receiving the prefix 10.0.0.0/23 while I have not allowed it in Route-map with ip prefix-list.
The config is:
